Well, more that I want to do liqid fuel for pulsejet and gaseous fuel for pulsepots... I'm in Costa Rica atm, so not doing anything but dreaming... Hey, Costa Rica seems like a good place to do some dreaming :D I'm only a week off blasting down through Europe on my KTM990! - so I'm dreaming of the ...

Great! I'll redesign on my trip for a full jacket, including water cooling of the "vortexifier". Good stuff, I don't know if the "vortexifier" will need water cooling because of the high temp tolerance of the resin - maybe one with water cooling, one without? What I did discover with water cooling ...

Nice work Mike - the design looks pretty proven dimensionally I guess we need to build it from something more heat resistant. If you want to send me the stl file I'll get it printed in resin when I get from Europe late sept/oct?

I am very keen on going to the bronze foundry. You know you can 3D print PLA and cast just like lost wax? Local art prof is doing that here in Santa Barbara. We should spend a day or two doing that! Do some suitably difficult to fabricate pulsers. Great stuff! - I hope to see Dave in Sept so hopefu...

OK here is the dewatering data from Dave the alchemist :D To get the water out of the ethanol, you need potassium carbonate. Add enough so that there is solid powder remaining at the bottom after a day or so. If it is liquid, you need to add more. Carefully pour off the dry ethanol, wash out the wet...

Hi Mike, Just a thought but the fuel you are using is ethanol? - very hydroscopic- Dave, a mate of mine, who is well into his chemistry, can process/refine it to remove almost all the water - I can ask him what it is he does to do this ( I recall he added something to the fuel and it solidifies at t...

That made my day Mike!! :D :D Cracking little device - I guess once you have finished tweaking it you could get it printed in metal if you wanted to? If I can clear my decks I'll get onto printing one on the resin printer and see how that stands up to the heat. Trying to get the upstairs spare room ...
